Steve,

They have these great electronic sniffers now that can find leaks down to 1/10 ounce per year.....they work great.  This is a new version of what I have.

Last expansion valve I did was on a '65 Marlin by buying a big expensive open and closed end wrench to fit on the evaporator core side and customized it so I could put an extension on it for more leverage= I was able to get enough leverage to pop it loose/worked for me.

I'm pretty sure that when R134a is mixed with the old refrigerant the combination forms crystalized abrasives in the system; this may the cause of your compressor seal failures... (some refrigerant leaks past the compressor pistons and gets into crankcase oil) -the entire system needs to be flushed/rinsed out with mineral spirits, blown out with compressed air, including the compressor crankcase to get rid of any trace of the older refrigerant and oils when putting new 134a into an older system.

Remember when using two wrenches in unison like that, one to hold the body and one to move the nut, the closer the two wrenches are to each other when trying to loosen the nut the better control and more power you will have. If the two are spread apart too far it puts your hands at a disadvantage.
